Can't boot Ubuntu USB on Lenovo Legion T5

I am trying to install Ubuntu 20.04(LTS) on a Lenovo Legion T5 28IMB05. I downloaded the ISO and installed it on a USB drive.

After selecting the USB on the boot screen, I found myself at the "grub>" prompt. How to I get past that to boot the Ubuntu installer?

ETA: Typing "exit" (per another question I found) continues on to boot Windows.

ETA2: I eventually tried the 18.04 installer, which was able to boot and install (after which the new Ubuntu system upgraded itself to 20.04.) Going through the "grub" manual:

My package_version is 2.04-1ubuntu 26.8 /boot has no files visible. /boot/grub has a boot.cfg but no *.mod files There is no file or directory visible for "vmlinuz" or initrd/initrd.img

ETA: My Ubuntu system is now working, but your question prompted me to double-check, and it seems to indeed still be running 18.04, despite the update-manager claiming it was moving me to 20.04. (Thanks for helping me notice that!)

I do have a new issue, which I was about to start researching, but now I'm not sure if I should try upgrading the version first.
For the record: My SSD, shared with Windows, is mounting both its partitions with the "noexec" flag, in direct defiance of the fstab entries. Both partitions also have a "msftdata" flag that gparted won't let me clear, that looks suspicious to me.

Is your Ubuntu system working after upgrading to 20.04? What is your question (what you want)? Please edit the original question to add more details.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
